A cast consisting of a lot of crystals, around which the tubular epithelial cells have been destroyed or lost (c and d) (PASM-Masson trichrome double staining and PAS staining respectively, both × 1000). Casts with strong staining of λ light chain (e) and no staining of κ light chain (f) (fluorescence micrographs × 400). A lot of crystals with different sizes and shapes in a cast (g and h) (electron micrographs × 8000 and × 4000, respectively)
